Yesterday, an overjoyed Antoine Arnault (son of LVMH chairman Bernard Arnault) posted on Facebook that his girlfriend, model Natalia Vodianova, is pregnant with their first child. Judging by his rampant use of exclamation points and smiley faces, he's pumped to be a dad:

Hi everyone, big news today!

Giving a little brother or sister to Natalia's 3 wonderful children is something we wanted so much: AND NOW IT'S HAPPENING! :)))

We're going to have our first baby next year!!! #4 for her but #1 for me... I'm a little stressed! She was tired the first 3 months but is fine now...

I hope he or she gets Mommy's looks (and beautiful heart!!!) and Daddy's sense of humor!!! Pleaaaaase not the other way around!!! :))))

He accompanied the post with five adorable pictures of the two of them, doing couple-y things like sleeping on a plane (first class, obviously) and sharing sunflower seeds, which is cuter than it sounds. Vodianova currently has three children from her previous marriage to British aristocrat Justin Portman.
